RF Transmit GREEN LED operates when Taurus
is transmitting an RF signal.
RF Acknowledge (if configured):
GREEN LED will Flash at high speed to indicate
that an acknowledgment has successfully been
received back form the receiver.
RED LED will Flash at high speed to indicate
that an acknowledgment has not been received
back form the receiver.

To Set the RF Transmission MODE
Notes
1. Range is dependant on many factors
including the mode of transmission.
Range can be reduced by 75% in built
up areas with poor antenna, and
environmental conditions.
2. Battery life quoted is approximate
based on 30 operations per day.
3. 918MHz devices do not have FSK
mode.
This sets the type of RF Transmission.
Possible options are FM, or LORA Modes 0
- 7. FM or LORA mode 0 provides the
quickest response; from Transmitter SW
pressed to Receiver Relay output.
LORA mode 7 provides the longest
operating range but with the longest time
delay of from button press to receiver relay
actuation.

To Set Continuous or State Change RF Transmissions
When a switch button is operated, TAURUS will
transmit a “Button Down” RF Transmission.
When a switch button is released, TAURUS will
transmit a “Button Up” RF Transmission.
Continuous Transmit
TAURUS repeat transmits “button Down” in
short bursts for as long as switch button is
pressed.
If the Acknowledgment is ON the receiver will
reply after each RF transmission burst.
This is ideally suited to momentary operation
where the receiver output needs to be active as
long as the user presses down a TAURUS
Button.
State Change Transmit
TAURUS transmits an RF transmission only when
the switch button is pressed or released (i.e. a
state change).
On each of these “state changes” TAURUS
transmits up to 4 transmissions, or, “RF
packets” (which can be seen by the GREEN LED
flashing up to 4 times,
If the Acknowledgment is ON the receiver will
reply immediately.
After receiving an Acknowledgment the TAURUS
will cease sending any remaining of the 4
transmissions.

RF Acknowledgment from Receiver - Warning!
When Acknowledgement is ON, TAURUS
requests an RF signal back from the receiver.
Whilst in theory if an RF signal can be
transmitted one way then it can be returned,
in practice occasionally the received acknowl-
edgement many not penetrate as well as the
Taurus transmitted signal.

To Set Acknowledgement Request
Acknowledgement Feature provides the user with
LED indication that the receiver has successfully
received the transmitters signal.
When activated the TAURUS Transmitter includes
an acknowledgement request within each radio
transmission.
The response from the receiver is indicated on the
transmitter via the RED / GREEN LEDs.

If enabled, TAURUS automatically transmits a
background “watchdog” RF Signal approx. every
~45 secs,
RF Solutions Receivers with a Watchdog
feature will hold a Relay contact “ENERGISED”
as long as Watchdog is regularly received
confirming the transmitter is in range and the
system is operating correctly.
When using Watchdog it may be useful to
incorporate a Power Switch to avoid premature
battery discharge.
A power switch can be incorporated if this is
required please contact our Sales Dept.
